1.1 本试验方法包括测定芳烃及其衍生物和相关化学品中的溴指数。 1.2 本试验方法适用于溴指数浓度达到100溴指数的样品。检测限（LOD）为1.5溴指数，定量限（LOQ）为4.9溴指数。 注1: LOD和LOQ使用D16 PTP程序的数据计算。LOD的估计包括实验室内的可变性。 1.3 以下内容适用于确定使用本试验方法的试验结果是否符合适用规范的目的，应根据实践中的四舍五入方法对结果进行四舍五入 E29年 . 1.4 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.5 本标准并非旨在解决与其使用相关的所有安全问题（如有）。 本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 有关具体的危险说明，请参阅第节 8. . 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 5.1 本试验方法可用作内部质量控制工具，并用于工业芳烃和相关材料的开发或研究工作。本试验方法广泛指示了烯烃含量。它不会区分脂肪族不饱和的类型。

1.1 This test method covers the determination of Bromine Index in aromatic hydrocarbons, their derivatives, and related chemicals. 1.2 This test method is applicable to samples with Bromine Index concentrations to 100 Bromine Index. The limit of detection (LOD) is for 1.5 Bromine Index and the limit of quantitation (LOQ) is 4.9 Bromine Index. Note 1: LOD and LOQ were calculated using data from the D16 PTP program. This estimate of LOD includes within-lab variability. 1.3 The following applies for the purposes of determining the conformance of the test results using this test method to applicable specifications, results shall be rounded off in accordance with the rounding-off method of Practice E29 . 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements, see Section 8 . 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 5.1 This test method is useful as an internal quality control tool, and for use in development or research work on industrial aromatic hydrocarbons and related materials. This test method gives a broad indication of olefinic content. It will not differentiate between the types of aliphatic unsaturation.
